本科生学年论文题目:从理论到应用——浅谈 lasso 模型 指导老师: 学院: 姓名: 学号: 班级: 从理论到应用—-浅谈 lasso 模型【摘要】回归模型是我们在处理数据中常用的方法
其中,Lasso 模型是一种适用于多重共线性问题,能够在参数估量的同时实现变量的选择的回归方法
本文从 lasso 模型的概念谈起,对其起源、思想、与岭回归的比较、通过 lar 的算法实现等方面进行了探究
另外还使用 R语言对简单案例进行 lasso 模型的应用
最后简述了 lasso 模型的讨论现状
【abstract】Regression model is our commonly used method in processing data
Lasso model is a kind of regression method for multiple linear problems, which can be used to achieve parameter estimation and variable selection at the same time
This paper starts from the concept of the lasso model, including its origin, ideas, and the comparison of ridge regression, through lar algorithm implementation, etc
In addition, using R language to solve a simple case through lasso
At last, the research status of lasso model is introduced
